According to the Book of Mormon, Lehi was a son of Helaman and was a Nephite missionary. He and his elder brother Nephi lived in the 1st century BC and had many missionary experiences together. The main events of their missions are recorded in the fifth chapter of The Book of Helaman. Lehi was named after his ancestor, Lehi, whose family immigrated to the New World from Jerusalem around 600 BC. Helaman taught his two sons to keep the commandments and to walk uprightly before God, as their namesakes had done. Known genealogy Mission to the Nephites Lehi's brother Nephi was the Chief Judge of the Nephites. After he resigned from the position, he joined Lehi in devoting the balance of their lives to the preaching of the Word of God.

As they taught with great power, many dissenters were confounded, humbled themselves, and eventually were baptized unto repentance.

Lehi and Nephi then traveled to the land of Nephi where a Lamanite army captured and cast them into prison – the same prison that once held Ammon and his brethren. Miracles at the Lamanite prison After many days of imprisonment without food, the Lamanites came to slay them. As they were approached, Lehi and Nephi were suddenly encircled about by a pillar of fire, which protected them from harm from their captors. Their hearts did take courage by this miracle and emboldened them to testify of God’s power and spoke marvelous words. As they did so, the earth and the walls of the prison shook exceedingly, a thick cloud of darkness and fear came over their captors, and a voice with perfect mildness call them to repentance.
